In general, the present invention contemplates a novel glazing construction embodying uprights and horizontally arranged panel supporting members constructed in sections and provision is made for mounting the panel supporting members in a manner such as to permit the glass or other panels to be erected from the interior face of the glazing structure.

This feature of the invention is of particular advantage in the construction of glazed side walls in high buildings, and is particularly useful in enabling panels to be easily and economically replaced. Provision is also made for mounting the sections of the panel supporting members upon the uprights in a manner such as to permit movement Fig. 9 is a detail of a modified form of one of the fastening members shown in Fig. '7 Fig. 10

Referring now to the drawings, the embodiment of the invention illustrated in Figs. 1, 2, 3,

5 and 7 comprises a single glazed structure of a type particularly adapted for industrial buildings and the like. In general, a series of upright fixed supporting members l0, preferably tubular in cross-section, are arranged to support individual panel sections l2, preferably of g1ass,between horizontal supporting members l4. The

supporting members M are connected to the uprights ID in a manner such as to suspend the panel sections thereon and to provide in effect a floating support for the panels l2 to permit relative movement thereof as will be described. glazing structure embodying aremovable decora- Provision is made for mounting the ja e t sections of the supporting members I4 upon the uprights In in a manner such as to permit the glass panels l2 to be inserted between the members l4 and secured in place from the interior face of the structure. As herein shown, each member 14 comprises an elongated section of fabricated sheet metal having an upper groove I6 adapted to receive the bottom edge of the glass panel formed by the upstanding walls i8, 20, joined at the bottom by the horizontally extended portion 22. The bottom groove 24 which is adapted to receive the top edge of a glass panel is only partially formed in the member 14 by the outer depending wall 26 and the horizontally extended portion 28, leaving the lower groove open on the inner face for a purpose to .be .described. In practice, the panel supporting members l4 are preferably constructed in sections of a length such that they may be erectedito overlap upon the face of the uprights ID to provide a space 30 between ends of adjacent sections thereof, see Fig. .5, and in some instances may be made of a length such as to extend across an intermediate upright so that the space will occur only at alternate uprights.

As herein illustrated, the panel supporting members 14 are arranged to-be snapped into place upon the outer face of the upright I6 and as herein shown, the latter are provided with snap-on clips 32 which may be secured to the uprights'by bolts 34. The snap-on clips 32 may be equal in width to the uprights and are provided with horizontally extended portions 36, 38

which are arranged to be yieldingly received bea tween the horizontally extended portions 22, 2'8

of the member 14 when the latter is urged into engagement therewith. The members M are secured in their assembled position by a vertical elongated cap member 40 which extends across adjacent panel supporting members and which" are secured to the uprights It] by through bolts 42. The through bolts 42 are received by a headed nut 44 extending'through the inner'wall of the upright as clearly shown in Fig. 2.

From the description thus far, it will 'be observed that provision is made for mounting the "panel supporting members uponthe uprights 10 and 'for clamping them in position against the outer face of" the uprights by'the cap members "Ml-and bolts '42. The structure is nowin readiness to receive the panels l2. Referring now to Figs. 2;7, 13 and 14, it will'be'observed that the glass panel I2 is slightly less in width than the width between adjacent uprights so as 'to permit the panel to be inserted therebetween and that the vertical edges of the glass panel maybe provided with strips 46 of any suitable cushioning material such as'asphaltic felt in order to form a weatherproof joint and a yielding support for the Vertical edges. In erecting the structuraan indiwall I8 of the member I4 is shorter than the inner wall26 so that any rain waterwhich might "be collected in the groove 16 will run out over The upper edge of the panel is then the top of the water wall l8 and thereby prevent any water entering through the structure.

As illustrated in Fig. 13, in the erection of the structure, provision is made for retaining the upper edge of the panel in assembled relation in the groove 24 and as herein shown, a snap-on retaining member 52 is provided which is arranged to snap into engagement with the panel supporting member l4 and to form the inner wall 54 of the groove 24. The retaining member 52 is of a length equal to or slightly less than the distance between two adjacent uprights and is the same .shape in cross-section as the snap-on clips 32 so ,thatwhen the member 52 is positioned in assembled relation, it forms in effect a continuation ofrsuch snap-on clips between adjacent uprights. Referring now to Figs. 2, 7, and 13, it will be observed that the vertical edges of the glass, being provided with asphaltic strips 46, are arranged to bear against the flanges 56 of the outer cap member- 40. In order to clamp the vertical edges of the glass against the flanges .56 and for securing the retaining members 52 in their assembled relation, angle members 58 are provided, each having-one leg 60 arranged to bear against the inner vertical edge of the glass and against the retaining member 52, the other leg being bolted to the upright Hi. The angle members 58 are made in sections arranged to extend vertically from one panel supporting member M to an adjacent member I14 and in overlapping relation therewith, and provision is .made for urging the leg 56 of each angle member into clamping engagement with the vertical edges of the panel and their supporting members in cooperation with the flanges 56 ofthe cap member. As herein shown, see Figs. 13, 14, the angle members 58 are secured to the uprights it! by screws 62 which extend through elongated holes 64 in the angle members, to permit lateral movement of the latter and into tapped holes 66in the uprights H]. A

washer 68 is provided under the head of each screw 62. In order to urge the angle member 58 into clamping engagement, a pair of eccentric disks Hi are provided which fit into openings .12 in the anglemember and are secured to the upright 16 by screws M. In assembling an angle member 58 to an upright H], the screws 62 are first screwed loosely into the upright in order to retain the angle member in a loosely attached gage-the holes -76 provided on the eccentric.

Thereafter, the screws 62 are tightened up to secure .the angle member in position, as shown in Fig. 14.

In some instances the angle members may be secured .to the uprights as illustrated in Figs. 9 and 10. -As therein shown, a pair of beveled eccentric disks -'!8 may .be employed arranged to fit into countersunk openings in -the angle member and which may be loosely attached to the uprights ,to retain the angle member in place. Thereafter, theeccentrics may be rotated as .before and the screws .86 tightened. This modification eliminates the necessity of providing the screws 62 for retaining the angle member in both clamping and fastening;

a ed-142 placesincethe beveleddisks" is may be used for In erecting the single glaze construction in a" building, the vertical frame members I may be erected in-spaced relation between the 11001 8I f t the uprights infthe' usual manner, leavingfan opening of the desired size for the glazing structure, and the siding maybe provided with upper and lower flashing strips 89 and 9| respectively aroundthe opening. illustrated in Fig. "I, the lower flashing strip 9| is arranged to fit into the groove 24 of thelowermost panel supporting member'I4 and the upper flashing strip 89 is arrangedto fitintofthe groove I6 of theuppermost member I4. In assembling I the glazed structure,lthe snap onclips 32 are first attached tothe uprights I 0 in the proper spaced relation and in alignment with each other. The members I4 may {then be snapped onto the clips 32 and the cap members 40 attached by the bolts 1 Hand nuts. 44. The individual panels I I2 may now be inserted between the members I4 by introducingthe loweredge' of a panel into a groove I I6 and resting the upper edge of the panel against the wall 26ofthe opengroove24 after providing the grooves with the plastic material 50 and affixing the weather strips46 to the vertical edges of the panels The snap-on retaining member 52 is then pressed 1 into engagement with the member I4 whereupon the angle members 58 are secured in clamping engagement with the inner surface of the glazed structure.

Thus it will be observed thatthe panels I2 may be erected from the interior of' the building to provide an emcient; economical and weather-proof structure. It will be observed that I when inserting the individual panel into agroove I6, the panel is raised above' theinner 'wall 20 and lowered into the groove below the outer wall I8, the latter being fof less height than the wall 20. This manner of insertingth'e panel'is made possible by having the member52inc1uding the wall54 of the groove 24 removably attached, as described.

From the description thus far, it will be observed that the adjacent sections of panelisup- I porting members I4 aremounted upon the uprights I0 in" a manner such as to permit movement or thesectionsunder expansion and contraction thereof. As hereinbefore described, the sectional members 14 are arranged to snap onto the clips 32 andtouoverlap the uprights I0 leaving a space 30 between adjacent sections as clear- 1y illustrated in Fig. This construction permits endwise expansion and contraction of both the panel I2 and the members I4 due to the sliding engagement of themembers I4 and the connecting clips 32. Expansion or contraction of thepanels in asvertical direction is permitted by reason of thefact that the upper edge of each panelonly partially fills the groove 24 providing 'arnple'spacefor movement of the panel. Thus I each glazed section is, in effect, floatingly mounted between four fixed points of support, represented by the clips 32 at each corner which are arranged to permitcthe members I4 to slide endwise thereonto permit independent expansion or contractionof the parts of each section without subjecting the structure to bending strains.

Furthermore, each individual panel I2 is fioat betweenthe grooves I6} 24 of the horizontal supporting members I4 thereby permitting expansion and contraction of a panel and its' supporting members tohtake placeat diiierent rates accordingto the expansion?characteristics of the material of :which the parts maybe composed.

' Referring nowto Figs. 1, 2, 3 and 11, the prescut glazed structure may be provided with a sliding panel 82. The slidingpanel may bearranged to exte'nd'between two adjacent uprights I01 and is preferably. offset with relationto the fixed panels I2. As illustrated i'nFigJ3 the sliding panel is arrangedto slide in grooves 84 formed by anglemembers 86*attached. to the uprights I0 by: screws 80 and by jamb pieces 90 also attached to the uprights byscrews '92. The forward edge I 94 of the jamb piece 90 is arranged to cooperate I with a flange 56 of the cap member 40, having a strip 3 of cushioning material 96 interposed therebetween. I As shown in Fig. 11', a head piece I 88. extendingbetween adjacent uprights and secured thereto by angle piecesI00 and screws I02,

is formed to receive the. adjacent panel supporting member I4. A guide I04 for the sliding pan-' e1 is provided on the uprights above the head .piecea98 to support the panel in its raised posig tion. Any usual or preferred means may be employed for holding the panelin its raised position such asthe usual sash weights, not shown. The

lower edge. of the :slidingmanel is arranged to cooperate with a sill piece I06 supported between the uprights and provided with an angle piece .I08 forming the outer wall IIO of a groove I I2 in ilwhich. the lower edge of the panel is supported.

.The inner edge of the sill piece is supported upon -,a sill channel II4 extending between the uprights as clearly shown in Fig. 11. The outer edgeof the sillrpiece: I06 isarranged to receive .the lower edge. of the cap member in overlapping relation and to extend over. the flashing strip 9|; formingthe edge of the adjacent siding material. I I

As hereinbefore stated, the present invention may be embodied ina double glazed structure,

and, as illustrated in Figs-24,6 and 12,.such an embodiment. may comprisean outer glazed section IIB supported upon the outer face of the uprights I0 and an inner glazed section II8 supportedfupon the inner faceofthe uprights I0. In

the illustrated embodiment of the invention the outer section IIB may comprise a unit similarvin construction tothe single glazed structure hereinbefore described. However, in the double'glazed construction a special cross-bolt I20 is preferably employed having horizontally. extended 1' and aligned portions I22 adapted to fit into grooves I24 provided upon .one face of panel supporting members I20for the inner glazed section H8.

I The panel supporting members I26 comprise exmembers. I I a In erecting the doubleglazed structure the truded metal sections having grooves. I28, I30 for the reception of the panelsbetween adjacent outerwall H6 is first assembled in the manner heretofore described in connection with the single glazed structure, leaving the cross-bolts I20 extending through the. uprights I0 and with the aligned portions I22 arranged in horizontalalignment to receive' the inner panel supporting members I26 as clearly shown in Fig. 6. The members I26are made in sectionsi'arrangedto overlap the uprights at their ends, leaving a space I32 there- .between. The members I26 are attachedto. the uprights by square washers I 34 and nuts I36 .which fit over the, bolts I20, the washers I34 being v tiolis I2 2.

When thenuts I;36 are tightened'up,themembers 126 are clamped a ainstxthe uprights I with the grooves I24 in en agement with the .aligned por- The panel receiving grooves I 28, I may'then be provided withsuitable plastic mate? rial I38 in preparation for receivingpa panel I2 and strips of suitable weatherproof material I40 arethen laid against the uprightstto form a yielding support for the edges of the paneLsuch strips extending vertically between the adjacent members I26. The individual panels I2 may now be inserted into the grooves by first introducing the upper edge of the panel intothe deeper groove I30 a sufficient distanceupwardly .so that the lower edgeof the panelxmayclear the shorter front wall I42 of the'lower memberI26. The

panel may then belowered into the groove I28 of the lower member I26 as illustrated in Fig. 12.

In order to cover the open spaces between the ends of adjacent panels I2 and between the adjacent sections of the supporting members I 26, each upright I0 is provided with a cap member I44. As best shownin Fig. 4,-each cap I44 is preferably of general U:-shape in cross-section, with flanges;

I46 engaging the ends of. the'several pairs of panel supporting members I 26. Each cap I44 is provided with .a plurality .of holes for receiving the projecting ends ofthe bolts I20, and the cap 4.111213 be securely positioned by knurled nuts I48 cooperating with the ends of the bolts I20. When securing a cap in position, suitable felt strips I50 are placed beneath the flanges I46 to fill the spaces between the flanges I46 and the also be vused-in constructing the inner section I I8 g if desired. It will be seen that in both types of structure the panel supporting members are permitted to expand or contract under the influence of varying weather conditions. In the structure embodying the extruded metal type of panel supporting members I26, the latter are permitted to slide on the aligned'portions 1220f the cross-bolt I20 under such conditions. It will also be observed that the glass panels I2 for the interior walls lI.8.may be made wider than the panels in .the outer wall, since in the former case it is not necessary to fit the innerpanels between the uprights I 0. As herein shown, the inner panels may extend in overlapping relation to the uprights and may be of a width equal to the panel supporting.

members. As hereinbefore described, in some instances it maybe desired to extend the panel supportingmembers across an intermediate upright in which case the panel supporting member may be fixed directly to the intermediate upright atthe center 'of such panel supporting member whereby expansion or contraction may take place in a lateral .direction toward or from either side of the center of the intermediate upright to which .the panel supporting memberis secured. I

Referring now to Figs. l5, 16, '17 and 20, a

modifiedembodiment of the present glazing structure particularly adapted for oflice, school or like buildings, is illustrated whichmay include .a decorative, hollow metal column or covering I arranged to be detachably supported adjacent selected or all of the uprights supporting the glazedstructure. The column IE0 is designed so that it may be easily detached from the glazing structure and replaced by a metal partition wall I62 of standard construction, and commercially available for this purpose, whereby partitions maybe erected or the location of such partitions changed at any time with minimum labor and I expense and at the same time retaining the general design and architecture of the building.

Both the column I 60 and the partition I62 are designed to blend harmoniously with the glazing structure and to form a compact and finished unit therewith whenassembled.

In the illustrated embodiment of the invention, referring particularly to the :single glazed structure, see Fig. 15, the glazed wall indicated generally by the numeral I64 may comprise a structure similar to that heretofore described in connection with the embodiment illustrated in Fig. 7, including the panels I2 and panel supporting members I4 arranged to permit the introduction of the panels from the interior of the building. As herein shown, in the erection of the present structure, the panel supporting members I4 may be snapped into position upon the snap-on clips 32 and clamped to the upright by a relatively wide cap member I66 and short ,bolts I68 which extend through the outer wall of the upright and are secured thereto by nuts I10.

Suitable spacers I12 may be provided between the upright and the cap member I66. The uprights I14 employed in the present embodiment are of general U-shape in cross-section, having laterally extended flanges I16 at the open end. As herein illustrated, the angle members I18 for clamping against the interior face of the glazed structure, adjacent the uprights I14, are. secured to the uprights in a modified manner which may comprise a pair of eccentric disks or washers I secured to the upright by screws I82 whichextend through an enlarged opening in the angle member. In assembling the angle member, the

screws I82 are attached loosely to permit rotation of the eccentrics which are adapted toengage the leg I84 of the angle member and to urge the latter into clamping engagement with the structure when the eccentrics are rotated whereupon the screws I82 are tightened up to secure the parts in place. 1

In order to detachably secure the column I60 to th glazed structure, a pair of elongated panel receiving members I86 are provided which may be welded or otherwise secured to the legs I84 of opposed angle members I18. The panel receiving members are provided with openings into which the opposed panel side walls I88, I90, of the column I60, are arranged to fit. The end wall I92 of the column may be provided with any suitable decorative design, preferably arranged to harmonize with adjacent partition columns I94 as shown in Fig. 17. The end wall I92 may be made up from individual sections pressed together in nesting relation as shown in Fig. 16 and one section I96 may be arranged to bear against the flanged portions I16 of the uprights I14. As herein illustrated, the column I60 may be removed from engagement with'the elongated panel receiving members I86 and the metal partition wall I62, having opposed panels I98, 200 may be inserted into engagement with the panel receiving members when it is desired to erect a partition wall.

-As herein shown, see Fig. 15, the upper and lower edges of the glazed wall 164 may behreceived by portions of the metallic: or othersiding has indicated at 202, 204,,and the inner face of vided with a portion M2 in engagement with the ceiling. The column I60 may be cut outqto fit snugly under the sofiit 206 and in engagement with thecorniceymember as: illustrated. The lower edge of the structure maybe provided witha sill 2| 4,arranged tobe detachably supportedupon a sill channel M6 and the space between the sill and thefloor maybe enclosed by any suitable paneledstructure H8. The enclosed space, between thesiding and the paneling. maybe providedwith insulation 2I9, if desired; 1 s In some instances, as illustrated in. Fig. 24, the detachably supported sill .2l 4 maybe extended a substantial distance from. the lower edge of the glazing structure and maybe provided with a sidewallzl9 extending from the edge of the sill to the floor to form a continuousvenclosed space along the wall. The space thus enclosed may be utilized for the heating permit air to escape: from the chamber 22!,

Suitable openings 225 may be provided in the outer wall topermit{fresh air to enterfrom the outside. As herein shown, the bottom wall of the chamber 22l may be closed by a datnper221 whichalso forms the upperportion of allower chamber 229. The base portion '23! Ofthfi side wall 2!!! may also be provided with grille work along sections thereof. a

In practice, the above described construction afiords several possibilities for treating the air entering from theoutsideu For example, when it is desired tocheat theairbeing taken in through the opening 225, "the damper 221 maybe opened to permit the air to pass overheating pipes in the chamber 22I before itpasses into'thebuilding through the grille 223. The air may be drawn in from the 1 outside and directed over the heating pipes by suitable ,fans, not;shown. In the hot weather, the air may beallowed to pass' over cooling units before passing intothe room. When the damper 221 is closed, the IOWCI'LChSJIlberm 229 may .beutilized "as a ductto receive air TU from the outside through theop'ening1225 and modified embodiment of the invention, as above described, may be, employed in corinection with a double glazed structure, and as herein shown, the double glazed embodiment maycomprise a pair of. opposed panel receiving members I86 secured to the angle members I18 and which are arranged to receive metal panel members 220' extending between the exterior and interior walls of the glazed structureato cover up the upright I14 and to present afinishedappearance. The metal panel members, 220 may besecuredto the upright by screws 222. e i It' will bewobserved that portions224 of the paneled members are disposed flushwith the flanges I16 of the upright l141to provide a surface against which the vertical. edges of the glass panels of the interior walls may rest, As shown in Fig. 22, the panel supporting members l4 for the interior wall may be mounted upon the upright I14 by engagement with a relatively wide snap-0n clip 226 secured to the flanges I16. In orderto clamp the verticaledgesof the glass panels against the flanges I16 and the portions 224, angular clamping members 228 are provided which may be secured to a the flanges by screws 230., The angular clamping members 228 areprovide d. with extended portions 232 which are arranged to be received withingrooves 234 formedin a detachable metal cap. member 236 corresponding; to, the column 60 of the single glazed construction. Thecap memben236 may be made ,up in sectionsasillustratedin crosssection in Fig. 18 and may include a 1flangedj.channel member 238 provided with cross bars 240,, 242 bolted thereto by bolts 244 and nuts 246. The, cross bars 240, 242 are ar-- rangedin spaced relation being provided with a spacer 2'46 therebetween, and the cross bars 240, 242 are arranged tobearagainst the panel sup- 1 porting members [4 and the upright flanges I16 respectively, at their ends. As shown in Fig. 19, the'metal capmember may be detached-from the glazed structure and replaced bya partition wall 250 whichis provided with grooves 252, 254

may

adapted toreceive the extended portions 2320f the clamping members 228. A

M illustrated in Fig. 23, another modification of -the. means for supporting the angle. members I18 may comprise a series of cross bars 260 sefcured to the face of the uprights I14. by bolts 262;. The crossbars 260 may, extend horizontally each sideflofctheupright :to provide surfaces againstrwhich. the, angle members I18 may be jsecuredfasby bolts26 4. Thismethod' of asseme blymakes it unnecessary to .use ,eccentricsfor other clamping means, since the angle, members may be drawn up bythe bolts 264 into yielding engagement with the vertical edges of the glass panels. i Y
